gm 13.5 2010 version
 

i bought this motor second hand and have been having trouble with it reducing power after a short run it doesnt get any hotter than 60 deg when this happens and the rotor feels fine, i suspect its a faulty sensor board so its up for sale as spares or repairs ideal if you have another one of these motors as you should be able to swap between the sensor boards, looks as new can in great condition possible cheap quick motor if you have the bits £25
